Built in the 17th century and located in southern France, the Canal du Midi is one of Europe's oldest canals still in operation and a UNESCO World Heritage site. For a long time, the canal served to transport merchandise. Today, amateur boaters can be spotted on the barges of this calm stretch of water. With 63 locks and hundreds of bridges, there's always something to admire. FRANCE 24 takes you on a tour of this centuries-old waterway.
